PRODUCTION • PROCESSING • HANDLING
To overcome the lack of documentation,
the Indonesian team contacted Sulzer Pumps UK. Te UK team was able to source all the documentation and data for the diesel pumps installed at the refinery. With this information, the team in Indonesia closely collaborated with the Sulzer Pumps engineering team in the USA. Building upon this, the USA team also delivered additional training to the customer’s team. Troughout the project, the Singapore
service centre acted as a central hub for all the different teams to organise their findings and recommendations. After close international collaboration, it was clear that the new duty point could be met without any modifications to the pumps themselves.
GEARING UP
Rather than modifying the pumps, new gearboxes would be used to increase the speed of the pumps to reach the new process requirements, which could be achieved well within the performance envelope of the units.
Armed with this information and a plan of action, Sulzer Indonesia carried out
detailed inspections of the units. Te team then conducted a full refurbishment of the eight pumps, bringing them back to as-new standard. New skid frames were fitted with efficient electric motors connected to gearboxes to deliver the desired speed increase, replacing the old diesel drives and steam turbines. To ensure a complete drivetrain package, Sulzer also installed new couplings and lube oil systems. Te rebuilt skids were a plug and play solution, allowing simple reconnection with existing refinery pipework, unlocking a quick installation and minimising time on site. Tis approach not only ensured a
reduced lead time on the project, but also meant the retrofit could be carried out at 50% of the cost of sourcing new pumps. Furthermore, the retrofit offered a time saving of five months compared to delivering replacement units. No modifications to the pumps themselves also allowed easy plug and play reintegration into the surrounding process equipment back at the refinery once work was complete. What had initially been a complex problem was solved with a straightforward solution that saved both time and costs.

MEETING DEMAND RELIABLY Updating the drive technology for the pumps ensured that the new duty point was also met with increased efficiency. By using the operational data for the pumps, the complex new performance requirements could be met with speed increasing gearboxes, with future system reliability assured. Te advanced engineering capabilities at Sulzer ensured that a complex application challenge was met with a faster solution that offered increased value compared to ordering all new pumps.
